Hope this helps you.
The genes of an organism can be
either a homozygous or a heterozygous one. When someone is a homozygous
dominant, it means that it has two copies of the same dominant allele. Homozygous
means that the organism has exact copies of the same gene allele.
Answer:
C if you plug it into the sentance its the only one that makes sense
When temp rises the liquid rises to temp and when temp drops liquid drops to temp
Answer:
the higher the diversity, the higher the populations of all the
photosynthetic organisms
Explanation:
Diversity in plant allows random mating also known as panmixia. It allows plant have equal chances of being mated too by any among them creating variations in the population. It leads to less fixed gene, reduce genetic drift leading to an increases population as some lethal gene may be lost due to recombination of gene among individual plant.
Where there is no diversity some gene becomes fixed leading to perpetuation of some traits that may be harmful in a population but diversity allows for the generation of new gene and allele frequency within a population.
Answer:In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.
Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes.
